Default [Q] Changing SE Linux from Enforcing to Permissive on Rooted Verizon GS5

Like everybody else, I just rooted my phone and now I'm trying to use it with my Pioneer Appradio 2. In order to do so, I need to change the status of SE Linux to Permissive. It's there a way to do this without an unlocked bootloader to flash a different kernal?
